Designation

Optional voltage conversion card with wide-range input. Input: 12-60 V DC. Output: 24 V DC / 2 A, 12 V DC / 6 A, 6 V DC / 6 A or 5 V DC / 6 A. Used when existing equipment requires a different operating voltage than the main system supplies. Maximum load capacity varies depending on the selected output voltage.

Area of use

For applications that require a different output voltage than that supplied by the battery backup or power supply. Allows flexible adaptation to different operating voltages to drive, for example, control boards, locks, sensors or other electronics that are not compatible with the system's regular output

Technical description

Compact option board for efficient voltage conversion with a wide input range of 48 V, 24 V or 12 V. The unit can be configured for output voltages of 24 V, 12 V, 6 V or 5 V depending on the application's needs. The board is optimized for high efficiency and minimal heat dissipation, allowing for seamless integration into existing systems. For high reliability, the product is equipped with integrated protection against short circuit and overload. Maximum load capacity is regulated by the selected output voltage. Voltage out can never be higher than incoming voltage
